Nutanix Prism Central Storage Policies
Prism Central allows configuring storage policies for virtual machines, covering settings like Replication Factor, Encryption, Compression, and I/O Performance. These policies can override container settings and are assigned to categories linked with virtual machines. The blog demonstrates limiting IOPS in a test VM to illustrate the impact of such policies, emphasizing their utility for managing performance in services like VM selling.

Single Sign On Nutanix Prism Central
This post provides a guide on setting up Prism Central (2023.4) to integrate with Microsoft Entra ID (Azure AD) for Single Sign-On (SSO) using SAML. It outlines the steps to configure SAML authentication by downloading metadata from Prism Central, creating a custom application in Microsoft Entra, assigning users or groups, uploading metadata back to Prism Central, and setting up role mapping. It also discusses limitations like the inability to add user groups to role mappings and suggests further refinements with custom claims and conditional access controls.
Nutanix Community Edition
Repurpose old Nutanix hardware
Revive old Nutanix clusters by installing Nutanix Community Edition. Document all node IP addresses and ensure proper switch connection. Use a bootable USB with MBR scheme or mount the CE installer ISO via IPMI. Select the correct disks matching the CE requirements and input the proper IP configurations during installation.
